Universal Rearview Housing With Interchangeable Viewing Device Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle rearview assemblies lack the ability to seamlessly accommodate a variety of rearward viewing devices, requiring multiple housing styles and increasing manufacturing complexity and inventory needs.
Innovation Solution
A universal housing with a connecting interface that allows for the removable and interchangeable attachment of different rearward viewing devices, including those with partially ground edges and outer rings, enabling a single housing to support various types of rearview devices such as electrochromic, prism-type, and display-type mirrors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple housing styles are used to accommodate different rearward viewing devices, then compatibility with various devices is improved, but device complexity and inventory requirements increase
Solution Approach 1:
The patent implements a universal housing design with a standardized connecting interface that can accommodate multiple types of rearward viewing devices (electrochromic mirrors, prism-type mirrors, display-type mirrors) through a single housing style, eliminating the need for multiple specialized housings while maintaining full compatibility across device types
2Adaptability or versatility
If multiple housing styles are used to accommodate different rearward viewing devices, then compatibility with various devices is improved, but inventory needs increase
Solution Approach 1:
The universal housing with standardized connecting interface allows manufacturers to maintain a single housing design in inventory that can serve all rearward viewing device types, significantly reducing inventory complexity and requirements while preserving the ability to support multiple device varieties
3Ease of manufacture
If a universal housing with connecting interface is used, then manufacturing complexity is reduced, but the ability to accommodate different device types may be compromised
Solution Approach 1:
The patent segments the rearview assembly into two independent components: a universal housing and interchangeable rearward viewing devices. The standardized connecting interface acts as the segmentation boundary, allowing the housing to maintain a simple, manufacturable design while the devices remain interchangeable through the common interface, thus preserving full device accommodation capability
Solution Approach 2:
The universal housing incorporates a multi-functional connecting interface that can interface with different device types (electrochromic, prism-type, display-type mirrors) through standardized mechanical and electrical connections, ensuring that manufacturing simplicity is not compromised while maintaining full adaptability across device varieties

AI summary
A rearview assembly kit for a vehicle having a housing. A connecting interface is disposed on a forward edge of the housing that is configured to removably connect the housing to any one of a rearview device having a peripheral edge with a bezel, or a rearview device having a peripheral edge that is at least partially ground away. A rearview device includes an outer ring proximate a peripheral edge thereof.
